Speedo correction.

[gmachinz]

If this is an auto-it's easy. Pull the cover off right where your speedo cable goes into on the side of the tranny-as you pull the unit out, you will see a plastic gear and it slides off the shaft. If you look closely, you'll see numbers like 52,61, etc.-those are the teeth count on the gear itself. If you swap to steeper gears, you want more teeth. If you go bigger in overall diameter, you want fewer teeth and vicey versa. They are color coded as to the teeth count and you should be able to goto any tranny shop that has a parts department and ask them for a few gears-they're cheap. You may need several before you get it right. -Jabin
